 CLEANING THE IMPELLER
If excessive deposits collect in the pump case you must dismantle the bottom part of the pump as
follows:
4. Remove the intake cage from the pump case.
5. Clean the impeller with clear water. Important: Do not put down or rest the pump on
the impeller!
6. Assemble is reverse order
 SETTING THE ON/OFF OPERATION POINT
The ON and OFF operation point of the float switch can be set by adjusting the float switch in its
latching holder.
Before you put the pump into operation, please check the following:
- The float switch must be installed so that the level of the ON operating point and the level
of the OFF operating point can be reached easily and with little force. To check this, place
the pump in a vessel filled with water, raise the float switch carefully by hand and then
lower it again. As you do so, note whether the pump switches on and off.
- Make sure that the distance between the float switch head and the latching holder is not
too small. Proper operation is not guaranteed if the gap is too small.
- When you set the float switch, make sure that it does not touch the base before the pump
switches off. Caution: risk of dry-running.
